(FILED UNDER THE ACT F IARCH 3, 1888, 22 STAT. L., 625.)

To all whom z't may concern Y Be it known that I, -CHAUNCEY M. Goon- RICH, major of engineers, U. S. Army, a citizen of the United States, stationed at Washington, D. C., have invented an Improvement in Knockdown Buildings, of which the following is a specification.

The invention described herein may be used by the Government, or any of its oilicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

his invention relates to Improvements In buildings of the knockdown, or ready to erect class in which the parts are constructed in multiple and adapted to be transported in crates, boxes or bundles to the locality where the building isto be erected and there assembled.

The principal object of the present invention is to improve and simplify the construction, decrease the time and labor required to erect the building, and increase the eiciency and utility of the same. p

Another object ofthe invention is to provide a structure of this character which may be rendered completely sanitary for use as a hospital without material structural change.

Another object of the invention is to provide a structure of this character formed in sections so that the length may be increased or decreased by adding or detaching sections.

With these and other objects in view the invention consists in certain new and useful improvements hereinafter described and specifically set forth in the claims, and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a transverse section of theimproved structure.

Fig. 2 is a sectional detail IllustratIng the construction of the oor and side walls.

Fig.'3 is a perspective view of the shoe for supporting the floor joist and the side and roof supports.

Fig. 4 is a view of the blank from which the shoe is constructed.

Figs. 5, 6 and 7 are sectional details illustrating the manner of fastening the purlin members, the roof covering and the inner wall or ceiling members in position.

Fig. 8 Is a detail side view of portions of the wall and ceiling members and a-portion of one of the 'oining strips, illustrating the3 manner of unIting and supporting the con fronting horizontal edges.

ig. 9 is a section on the line 9-9 of F ig. 8.

`igs. 10 and l1 are cross-sectional detail views.

The improved structure comprises in general longitudinally directed sill members in sections, joist members in sections and bearing at their ends upon the sills, side and roof supports in sections and preferably semioircular in outline, a plurality of purlin members in sections and extending transversely of the wall and roof supports, wall and roof sectIons engaging over the wall and roof supports, and a ceiling in sections and bearing upon the inner faces of the wall and roof supports. f

The sill members are represented at 10 and extend longitudinally of the building at each side. Where the building is relatIvely short the sill members will each be in one piece, but for longer buildings the sill members will be in sections abutting end to end and the ends coupled by suitable means.

The joists are represented at 12 and bear at their ends over the inner portions of the sills, as shown. l

If the buildings are relatively narrow, the joists will each be in a single piece, but for wider buildings each joist will be in two or more sections abutting end to end with channel shaped coupling members 413 engaging and supporting the adjacent ends and secured thereto by bolts or rivets or other fastening devices. The couplin members will be further supported by locks bearing upon the ground, if required.

The walls and roof supports are represented at 14 and formed of L bars arranged in pairs with the confronting webs at spaced intervals.

When the side walls and roof are semicircular in outline the supports 14 are correspondingly curved as shown in Fig. 1, and in relatively large buildings the members 14 the outstanding we bs at each side of the building.

Bearm upon the sillmembers and extending geneath each of the ends of the joists 1s a shoe device formed initially as shown in Figs. 3 and 4 of a plate of sheet metal includlng a central body portion 16 with clefts 17 whereby wings 18 are released at one side of the clefts and adapted to be bent at right angles to the body portion, the joist bearing upon the central or intermediate part 16 and the wings 18 bearing upon opposite sides of the'fjoist. The portion of the plate at the opposite side of the clefts is formed with an intermediate recess 19 and the partsof the plate at opposite sides of the recess bent at ri ht angles to the plate to form wings 20. T e lower ends of the lateral webs of the supporting members 14 are seated in the spaces between the wings 20 and 18 while the outstanding webs are located in the recess 19.

The bearing plates with their wings y18 and 20 form shoes or supports for the joist and the supporting members to effectually couple the joist and the supporting mem ers to the sill.

The oor of the building restsl upon the joists 12, but as the specific construction of the i'loor is the subject matter of a separate application it is not further described. The lioor will preferablybe in sections corresponding in width to the wall sections.

The supporting members 14 will generally be spaced about 4 feet from center to center, and to facilitate the assembling of the units which form the com leted structure, the floor sections will pre erably correspond'in width to the spaces between the members 14.

Attached to the inner faces of the supports 14 is a ceiling or inner covering, preferably formed of sections 25 of laminated or wall board material. The sections of wall material Will generally correspond in along the edges, the wall sections 25 are provided with recesses to receive clamp bolts 27, and bearing over the joints between the Wall sections are'binder strips 28. The bolts 27 are headed at their outer ends as shown at 27 "to bear upon the webs 14, and extend at thelrinner ends through the binder strips 28 and threaded to receive clamp nuts 272.

By this means the ceiling and wall members are secured in position and may be detached without disturbing the other por- -tions of the structure.

receive binding nuts 32 which engage the adjacent faces of the strips. By thls means the wall and ceiling supports and the inner wall or cover sections are firmly connected and supported with one set of the'bolts.

The roof portion of the improved structure is formed of plates 33 of corrugated sheet metal overlapping at their sides and ends and bearing upon the purlins 29 at their overlapping parts, and at intermediate points, if required.

The roof plates are coupled to the purlins by hook bolts 34 extending through the overlapping portions of the plates and engaging the purlins by their hooked ends, and secured in position by clamp nuts 34 bearing upon the roof members, as shown.

By the arrangement of parts shown the roof plates may be independently connected to the purlins and may be independently attached or detached without disturbing other portions of the structure.

The improved building is provided with suitable closures for the ends, not shown as they form no part of the present invention.

As before stated the wall and ceiling supports 14,-the roof section 33, the wall and ceiling members 25, and the floor. sections 21, are preferably of uniform width, so that the length of the building may be increased practically to an unlimited extent by simply multiplying the sections. Thus, given a plurality of the wall and floor sections and two sets of the end sections, a building of any required length may be quickly erected and the parts as quickly disconnected, when re uired.

n the higher class of buildings, or those in which a plurality of the Wall members 25 are required for each frame section, their contiguous ends will be coupled by rooved or channeled strips 46, as shown 1n igs. 8 and 9.

Having thus described the invention what is desired to secure by Letters' Patent is:

1. A knock down building, vincluding joists, supports, and a connectingmember for securmg the supports to the jolsts com- .los

ranged 1n pairs and joined together along;l

adjacent flanges to form substantially a T- beam, and a connecting member comprising a body portion, wings formed along the longitudinal edges of the body portion and bent at right angles thereto to form with the body portion a. socket for the reception of an end of the joist and Wings formed at one end of the body portion and bent at right angles thereto, said Wings spaced from the first mentioned Wings to provide a space for the reception of the flanges of the sup- 25 ports.
